T60p (sometimes) BSOD when shutting down

[tnkflx]

Hey Everyone,

Since I ran System Update a week or a week and half ago, my T60p started to BSOD when shutting down. Not all the time, just sometimes (let's say 50/50 :p). The BSOD does seem to look the same everytime...

I know that System Update installed new Wifi and Ethernet drivers. I've already uninstalled and reinstalled those to no avail...

Any idea what might be going on? Has anyone seen this also?

Hmmm, according to Windows debugger, it's the new ATI drivers that are at fault:
